The Los Angeles Times: The South Korean tech giant, joined by three Chinese partners, dominated this year's show that had a record number of exhibitors despite being called a failure before it even opened.

The reason for the grim diagnosis by some pundits and analysts was simple: Many of the most influential tech companies in the world didn't officially participate: Apple Inc., Microsoft Corp., Google Inc., Facebook Inc., Amazon.com Inc.

Although this year's show won't be remembered for any ground-shaking innovations or jaw-dropping product launches, it did highlight several ways the global technology industry has evolved. From the rise of Samsung Electronics Co. to the decline of 3D as a critical selling point for TVs, the show still offered several important insights.
